To all whom t may concern Be it known that I, O'i'ro WALTER, a subject of the King of Prussia, and residing at Hanover, Germany, have invented certain new and useful'lmprovements in Vulcanizers, of which the following is a specifica tion.

My invention relates to vulcanizlers and is particularly designed for carrying out the .0 processdescribed in my Patent 1,052,430, dated Feb. 4, 1913, of which the present application is a division.

e new vulcanizing mold 'permitsl of placing in the heating chamber of the mold at the predetermined vulcanization spot a greater or less quantity of the pre-heated live coals which serve to produce the vulcanization. Beneath the coals supporting pins or aA grate may be arranged in the vulcanizer, which according to the form of the body heated or te vulcanization spot may be specially shaped.

Instead of live coals, many other suitable sources of heat may be substituted to secure vholes Z and serves to prevent overheating. The rubbery body that is being treated is clamped in the usual way between the base e' and the bottom of the heating chamber and drei m may be arranged between the heating chamber and base, which will serve to sup` A coals are placed is offset at n in order to keep 'the coals as thickv as possible at the spot' y to b e vulcanized and' thusv accelerate the vulcanizat'ion process.

gas heated body, the form of which corresponds to the surface to be vulcanized. An electrically heated body, the heating source of which is preferably separately arranged, may also be employed;

In the accompanying drawings, Figure 1 is a side elhvation partially in section of a device for.. Lulcanizing tubes; Fig. 2 is a vertical crossfsection of the same; Fig. 3 is a plan View of the lower member of the heat- 1ng. chamber; Fig. 4 is a vertical section of a vulcanizer for repairing tires; Fig. 5 is af `plan thereof, partially in section; and F ig.` G is a side elevation of a modification of the heating means.

Referring to Figs. l to 3 the invention is e 85 In Fig. `6 a burner 0 is shown for heat-t ing the mold by gas instead of'by charcoal. In this arrangement the face plate' p is pref- ,shapes may be employed which' are suitably 9o shaped to the object to'be heated.
